SQL SERVER: SELECT INTO Statement to copy data from one table and insert into new table

Introduction: In this article I am going to share how to copy/select data from all or selected columns of one table and insert into a new  table in SQL. 

In previous articles i explained How to Insert multiple records in table in single insert statement and INSERT INTO SELECT FROM statement to copy data from one table to another and Get second, third, fourth or nth highest salary of employee and Self join example in sql server and Multiple ways to join first, middle and last name in sql

Description: The SELECT INTO statement selects/copies data from one table (Source) and inserts it into a new table (Destination).

Implementation: Let’s create a sample table and perform the desired operation.

  --Create a table(Source)

GO

CREATE TABLE tbBooks

(

    BookId        INT NOT NULL IDENTITY(1,1) PRIMARY KEY,

    BookName   VARCHAR(100),

    Author         VARCHAR(100),

    Publisher      VARCHAR(100),

    BookPrice     DECIMAL(10,2)

)

--Add some dummy data into the table

GO

INSERT INTO tbBooks VALUES

('Asp.Net','Ajay','Rozy Publication',1200),

('C#.Net','Sahil','Jai Publication',1000),

('VB.Net','Nancy','Rozy Publication',970),

('MVC','Sahil','Amar Publication',1480),

('JAVA','Supreet','Sam Publication',850),

('PHP','Parvesh','Maya Publication',800)

 --Check inserted data

SELECT * FROM tbBooks 

BookId	BookName	Author	Publisher	BookPrice
1	Asp.Net	Ajay	Rozy Publication	1200.00
2	C#.Net	Sahil	Jai Publication	1000.00
3	VB.Net	Nancy	Rozy Publication	970.00
4	MVC	Sahil	Amar Publication	1480.00
5	JAVA	Supreet	Sam Publication	850.00
6	PHP	Parvesh	Maya Publication	800.00

Note: We can copy data from all or any number of columns from one table and insert into a new table that will be created automatically.

Copy all data from one table and insert into a new table:

SELECT * INTO tbSelectedBooks FROM tbBooks

Note: A new table "tbSelectedBooks" will automatically be created with the column names and data types taken from the SELECT statement. All the data from source table(tbBooks) will get copied into destination table(tbSelectedBooks).

--Check inserted data

SELECT * FROM tbSelectedBooks

BookId	BookName	Author	Publisher	BookPrice
1	Asp.Net	Ajay	Rozy Publication	1200.00
2	C#.Net	Sahil	Jai Publication	1000.00
3	VB.Net	Nancy	Rozy Publication	970.00
4	MVC	Sahil	Amar Publication	1480.00
5	JAVA	Supreet	Sam Publication	850.00
6	PHP	Parvesh	Maya Publication	800.00

Copy only certain columns data from one table and insert to a new table:

SELECT BookName, BookPrice INTO tbBookList FROM tbBooks

--Check inserted data

SELECT * FROM tbBookList

BookName	BookPrice
Asp.Net	1200.00
C#.Net	1000.00
VB.Net	970.00
MVC	1480.00
JAVA	850.00
PHP	800.00

Copy data from one table and insert to new table based on condition:

Suppose we want to copy and insert only those records from tbBooks table where Book price is greater than 1000 then the query will be as:

SELECT BookName, BookPrice INTO tbBookListDemo FROM tbBooks WHERE BookPrice >1000

--Check inserted data

SELECT * FROM tbBookListDemo

BookName	BookPrice
Asp.Net	1200.00
MVC	1480.00

Change column names in the new table to be created:

By default SELECT INTO Statement creates a new table with the same column names as defined in source table. But we can change the name using AS clause:

SELECT BookName, BookPrice AS Price, Author AS AuthorName INTO tbBookData FROM tbBooks

SELECT * FROM tbBookData

BookName	Price	AuthorName
Asp.Net	1200.00	Ajay
C#.Net	1000.00	Sahil
VB.Net	970.00	Nancy
MVC	1480.00	Sahil
JAVA	850.00	Supreet
PHP	800.00	Parvesh
